Merge tag 'realview-base-armsoc-1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator into next/multiplatform

Merge "Realview multiplatform support" from Linus Walleij:

The board and infrastructure changes for RealView
multiplatform and extended DT support.

* tag 'realview-base-armsoc-1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator:
  ARM: realview: add an DT SMP boot method
  ARM: realview: select SP810 and ICST for the DT variant
  soc: versatile: add support for the PB11MPCore
  clk: versatile-icst: add device tree support
  clk: versatile-icst: refactor to allocate regmap separately
  clk: versatile-icst: convert to use regmap
  ARM: realview: remove private barrier implementation
  ARM: no longer force unbuffered DMA for realview
  clk/realview: stop using machine headers
  ARM: realview: don't map undefined PCI registers
  ARM: realview: remove sparsemem hack
